抄録

Denitrification of nitrified wastewater was investigated by using a bioelectro reactor which consisted of immobilized denitrifying bacteria electrode as cathode and carbon electrode as anode.<br>Experiments were performed to investigate the effects of electric current, influent nitrate concentration, HRT and ORP on the denitrification rate, nitrite production and hydrogen utilization.<br>The denitrification rate and hydrogen utilization were varied with mol ratio (λ) of hydrogen and nitrate which were supplied to the bio-electro reactor, and those muximum values were observed at λ=1.4. Nitrate remained under λ=1.4 in the effluent, and residual hydrogen occurred upper λ=1.4.<br>The nitrite production was not effected by change of λ value and ORP and DO have to control in the proper values because nitrite production was enhanced in the higher value ranges of ORP and DO.
